Kagome spin liquid: a deconfined critical phase driven by gauge fluctuation
Yin-Chen He, Yohei Fuji, Subhro Bhattacharjee
We investigate the nature of quantum spin liquid (QSL) phase of the spin- nearest-neighbor XXZ antiferromagnet on the kagome lattice. Recent numerical calculations suggest tha…
Kagome chiral spin liquid as a gauged U(1) symmetry protected topological phase
Yin-Chen He, Subhro Bhattacharjee, Frank Pollmann +1
While the existence of a chiral spin liquid (CSL) on a class of spin-1/2 kagome antiferromagnets is by now well-established numerically, a controlled theoretical path from the latt…
Bosonic Integer Quantum Hall effect in an interacting lattice model
Yin-Chen He, Subhro Bhattacharjee, R. Moessner +1
We study a bosonic model with correlated hopping on a honeycomb lattice, and show that its ground state is a bosonic integer quantum Hall (BIQH) phase, a prominent example of a sym…
